Nice,
But the one I would like is #93111018501, rubber elbow that connect to turbo re-circulating valve.
Anyone found a source for new one?_________________1976 924 N/A ROW SOLD

There is nothing special about it. Use any of the OEM rubber elbows on the top of the engine, almost the exact same thing. Or use a silicone elbow from any performance supplier which will last far longer than a rubber option._________________1980 931 - forged pistons, Piper cam, CGT turbo, 951 ducted FMIC, custom intake, Mittelmotor dizzy & cam pulley, H&S exhaust, GAZ Gold, Fuch'ed, Quaife LSD

Theres' nothing special about it. 15mm either end. Confirmed. Same as head breather and vacuum limiter elbow 931 110 181 00

One of the first things I did to my 931 was change all the OEM elbows to Samco silicone.
They were still fine 10 years later when I pulled everything apart, including the elbow for the recirculating valve.

I always wondered why there was such a big fuss over essentially generic hoses?

This does seem to be a running theme with the 931 though. There are always alternatives to OEM NLA parts if you look or think hard enough.

I believe the reason there are so many different part numbers for the OEM elbows is because the "leg" dimensions and the radius dimensions are different for the different part numbers. This is just a guess from looking at old worn-out elbows.

Regarding silicone elbows, I have not been able to find any with a tight enough radius to suit my taste. When the radius is too big, you have to trim the leg in such a way that doesn't leave enough material for proper clamping, or the hose can end up crimping, causing stress fatigue. I discontinued reselling silicone elbows for this reason, but if others have found suppliers with suitably tight radius, I would love to know who carries them. I've struck out with Samco and Vibrant.

If you are looking for a really inexpensive alternative to the OEM 14mm elbows, Dorman part number 46051 is a rubber PCV 90 degree PCV elbow with a 0.58" inlet and outlet (14.732mm). It appears to have a sufficiently tight radius and enough leg that could be trimmed shorter if necessary.

The straight sections should be replaceable with any suitably sized oil-resistant rubber or silicone hose that can be trimmed to fit.
